Scientists Create Building Blocks for Powerful Antibiotic

Topic: Biology

Researchers from Otto von Guericke University Magdeburg created key building blocks of a powerful antibiotic called Neosorangicin A. This breakthrough could help combat antibiotic resistance.

Chemists from Otto von Guericke University Magdeburg have made an important discovery in the fight against resistant bacteria. The team, led by Professor Dr. Dieter Schinzer, produced key building blocks of a naturally occurring substance called Neosorangicin A in the laboratory for the first time.

This achievement is significant because it allows scientists to develop Neosorangicin A as a potential reserve antibiotic to combat antibiotic resistance in the future. To create this complex molecule, the researchers used a method called relay synthesis. Instead of making the entire molecule at once, they broke it down into smaller sections and combined them later.

Neosorangicin A is produced by myxobacteria to compete with other microorganisms. It has been shown to interfere with bacterial RNA polymerase, which is essential for bacteria to read their genetic information and multiply. This makes Neosorangicin A a promising candidate for developing future reserve antibiotics.

The challenging part of creating this molecule was its complex three-dimensional structure. The molecule contains 16 chiral centers, where the spatial arrangement of atoms must be precise. Even small deviations can affect how well the substance works.

Schinzer and his team developed a convergent synthesis strategy to create Neosorangicin A. They produced three highly complex key building blocks separately and combined them at the end of the process. This required up to 19 chemical reaction steps.

Why It Matters

Antibiotic resistance is a growing concern worldwide, including in India. This breakthrough could lead to new treatments for bacterial infections and help combat antibiotic resistance.
